Headed out to Nantucket this Saturday, 8/2. Has anybody anchored there? We are not sure of our arrival day or time and don't want to reserve a mooring. Plus we prefer anchoring.... How is the ground? What type of anchor(s), We have delta anchors with 60' of chain that has never failed us on our 36' Regal. We have not been there in a few yrs, any changes? Well, except the obvious of the 70' boat Pascal delivered.
